ASSIGNOR TO AMERICAN STOVE-COMPANY, OF ST. LOUIS,,IISSOU 'EI, ACORPORATION OF NEW JERSEY I RADIANT HEATER Application ,filed ma 12,

This invention relates to certain new and useful improvements in radiantheaters and more particularly to the radiant element therefor, theobject being to provide a ra *6 diant heater with a plurality of radiantele ments arranged side by side, each being provided with a flashopening in each of its sides ha-ving'means for deflecting the flameeither right or left so as to obtain an instantaneous flash from oneelement to the other, thereby providing means for instantaneouslyignitingall of the elements irrespective of which element is-initiallyignited.

Another object of my invention is to pro- Vide a radiant element with aflash opening in each of its sides, one half of each opening beingprovided with a deflecting portion so that the flame ofcombustion can bedeflected from the burner in either direction,thereby overcoming thedifficulties existing in devices of this kind now in use, as no means inprior devices is provided for deflecting the flame to cause aninstantaneous flash. v

A still further object of the invention is to provide a radiant elementwhich can be manufactured very cheaply, the flash opening and thedeflecting means being formed integral therewith and formed when theelement is molded so that when a series of these elements are arrangedside by sidewithin the frame of the heater any one of the elements canbe ignited, as for example'the right hand element or the left handelement, and when ignited, an instantaneous flash is obtained betweenthe respective elements so as to prevent gas from escaping.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

Figure 1 is a section, partly in elevation, of a portion of a radiantheater constructed in accordance with my invention;

Figure 2 is a section taken on line 2- of Figure 1 showing thedeflecting elements of the respective flash openings in order to flashin both directions;

Figure 4 is a detail perspective view show- Figure 5' is a verticalsection through a portion of a series of radiant elements showing inplan view the respective flash opening if and deflectors therefor;

Figure 6 is a plan View in section showin the grille of the frontportionof each radiant element in order to illustratethe inclineddeflecting portions of the roofs of the flash openings; and j i Figure 7is a top plan view of a portion of the burner. i V In the drawings 1indicates a frame of heater, 2 the burner, and 3 the radiant elementswhich are arranged side by side, the end elements abutting the frame soas to close the flash opening formed in its adjacent side, whereby I amable to manufacture all of the elements identically and thedescriptionof one will be sufficient for all. The elements are preferably oblong inshape, being formed hollow with a solid back a and a foraminated front5, which as herein shown is in the form of a grille, the bars of thegrille and the in ner face of the back being provided with cone ablyformed of refractory material and these radiant elements are disposedover the jet portions 2 of the burner as clearly shown in Figure 1, thejets or burner tips beingarranged in clusters asclearly shown in Figure7, a burner tip or jet A being arranged at each end of the clusteroutside the remaining burner jets so that the gas flowing through thesejets will have a tendency to follow the inner faces of the sidewalls ofthe radiant elements so that when ignited, the flame of combustion canbe deflected through the flash I opening as will be hereinafter fullyvdescribed.

A flash opening 8 is formed in each of the Side walls of the elementswhich are adapted to registerwhenthe elements are arranged side by sideand half of the roof of each opening is provided with an inwardlyextendingdeflecting p rtien and byreterring to Figure 5, which shows aface view of a pair of elements cut longitudinally through the flashopening, it will be found that the roof of each back portion on theright side is provided with a deflector 9 having an inclined face 10which registers with the inclined wall 11 of the flash opening of theadjacent element.

By referring to Figure 6, which is a plan view of the inner face of thefront portion of each element-,it will be found that each of the roofsof the flat portion of the flash opening is provided with a deflectingportion '12 which has an inclined surface registering with the inclinedwall 13 of the roofof the flashf opening so that when the element iscast in the form of a hollow rectangular body, the deflecting membersare formed in the roof of vthe flash opening, some of which slant totheleftand some of which slant to the right so that when one of theradiant elements is ignited, the flame of combustion traveling up theside walls will be deflected instantaneously into the adjacent radiantelement whereby I am able to ignite all of the elements instantaneouslyirrespective of which of the elements is initially ignited.

By referring to Figure 4,11 have shown the end jet opening of the burnerA in position under a portion of a radiant element constructed inaccordance with my invention and itwill be seen that as the flame ofcombustion rises from this jet, it strikes the deflecting elementso'that it is deflected to the left into the element arranged to thatside. As theelement of the other side has an inclined .de- I fleetingelement which is disposed over the other jet opening A of the cluster,when the gas is, ignited and the flame of combustion rises, it strikesthe inclined deflecting element so that it is deflected to the rightthrough the flash opening of the adjacent radiant element and it will beseen that .by this construction the elements are constructed exactlyalike and can be arranged side by side and when so ar-v ranged a'radiant heater is provided with flash openings having deflecting memberswhich will deflect the flame instantaneously so that any oneof theradiant elements can be initially ignited and the remaining elementswill be instantaneously ignited by the flash of combustion, which willtravel transversely through the flash openings by being deflected by theinclined deflecting portion.

From the'foregoing description it will be seen'that' I have provided anovel form of radiant element which is. formed of refrac- What I claimis:

1. A radiant element for radiant heaters comprising an oblong bodyhaving a solid back and solid walls and a foraminated front and an openbottom, each side wall of said element being provided with a flashopening, the upper wall of each opening having portions inclined inopposite directions, one of the inclined walls of each of said openingsbeing extended inwardly intosaid hollow element;

2. A radiant heater comprising a burner having jets arranged inclusters, the end jet of each cluster being arranged beyond theremaining jets and a hollow radiant element disposed over each clusterof said burner having flash openings in its sides provided with inwardlyextending deflecting portions disposedover the end jet of each clusterof said burner for deflecting the flame of combustion laterally throughsaid flash openings.

,3. A radiant heater of the kinddescribed comprising a burner, a seriesof hollow radiant elements disposed above. said burnerand arrangedsidevby side, said sides having registeringopenings,said openings ofadjoinvmg members provided with upwardly inclined projecting members fordeflecting the flame from one radiant element to the other radiantelement, for the purpose described.

4. A radiant heater of the kind described comprising-a burner, a seriesof vertically 7 hereunto affix my signature. V

' MINARD A. POSSONS' tory material having flashopenings in its f sidewalls, each element being constructed exactly alike so that they can bereadily assembled side by side in order-to produce a radiant heaterhaving flash openings which.

will flash instantaneously, thereby overcoming the difliculties existingwith heaters of this kind now in use.
